Patent DE-2924300-A1 (DE)
Title: Electric steam iron - with valve seat integral with bottom of plastic water container
Inventor: RADER ARMIN ING GRAD
IPC: D06F75/14
Filed: 1979-06-15
Abstract: An electric steam iron has a water container, made of thermoplastic material with a valve seat which is an integral part of the container bottom. The area surrounding the valve seat is designed as a concentrically corrugated diaphragm. The valve rod itself is stationary and access for water to the steam evaporation space below is obtd. by removing the seat downwards. A flexible hose, supported on the inside by a corrugated metal tube, forms the joint from the valve to the evaporation space. This reduces the number of parts to be assembled and reduces the time required for it.

Title: Adaptor testing condition of telephone line by TV set - uses opto-electronic isolator for short sampling pulse
Inventor: OCHOJSKI PETER ING GRAD
IPC: H04M11/08
Filed: 1979-10-20
Abstract: An adaptor unit (Z), interposed between a t.v. set for the reproduction of data and a telephone subscriber station is equipped with a unit comprising power supply, a call-selector data transfer circuit and electro-optical coupler (SV, AWD, DUE, OK). A test circuit (PE) enables the set to indicate whether or not the loop circuit in the telephone line has been set up. To this end circuit group (PE) contains two opto-electronic couplers normally shunted by a contactor of a relay, e.g. a reed relay, which is in series with a test potential applied over a connection line (S1) from the TV set. This test potential need not last longer than about 20 microsecond. Due to the inertia of the reed relay in the test circuit (PE) the time the relay contactor opens is longer but well below a period of 1 ms. During this time the l.e.d.(s) of the coupler are in series with the line current loop, but this is tolerable for the telephone system.

Title: Data transmission by frequency division multiplex methods - uses integrator circuit for trapezoidal wave shaping to avoid interference
Inventor: GIROLAMI GIORGIO
IPC: H04L25/03
Filed: 1980-01-31
Abstract: The method and circuit are for the transmission of data over a frequency division multiplex network using a modem and avoiding problems such as increasing adjacent channel noise, beating with group pilots when the data channel is the first or sixth in the group. The square wave pulse of T/2 and width peak voltage Vi is transmitted to line in a trapezoidal form with leading edge rise time and trailing edge decay times of (t1) each which is inversely proportional to (DELTA F) and avoids pilot interference, where (DELTA F) is the carrier to pilot frequency difference. and 2 t1 + t0 = 2/DELTA F + t0 where t0 is the pulse width at peak when trapezoidal. The circuit to modify the pulse shape uses a differential amplifier (A) as a Miller-Integrator with input resistor (R1) and input/output capacitor (C1). Parallel to the capacitor (C1) are a switching diode (D1) and a switching transistor (TR1).

Title: Permanent storage container for radioactive waste - has waterproof layer between inner container and outer concrete block to prevent leaching and permit later transportation
Inventor: GRAHMANN UWE ING GRAD
IPC: G21F9/36
Filed: 1980-03-31
Abstract: A final storage structure for the disposal of radioactive waste comprises a hollow concrete block, inside which a container for the radioactive waste is mounted. Between the container and the block there is an all-round intermediate space, which is completely filled with a layer of water-repellent and water-impermeable filler material. Pref., this filler material is a cast or poured material, more specifically a bitumen mixt., clay mixt., plastics, casting resin etc. The pref. thickness of this intermediate layer is 0.5-5 cm. Used for the long-term storage of radioactive waste. By providing a completely water-repellent layer between the outer concrete block and the internal container, the risk of water penetrating through the container and causing a breakdown of the container and contents with subsequent leaching into the surrounding ground is eliminated. Suitable for "recoverable stores", from which the radioactive waste can be removed, if desired, even after very long storage periods.

Title: Combined solar and wind-driven energy generation plant - uses raised weights to store energy for subsequent electrical current supply
IPC: F03D9/16
Filed: 1980-04-15
Abstract: The generation plant is used to provide mechanical or electrical energy for moving ballast wagons from a lower to a higher level. The return of these wagons from the higher to the lower level under the force of gravity is used to drive generators for supplying electrical energy. The wagons may be shunted between two track sections at different heights via an inclined track section or via an elevator. Alternatively, the ballast wagons are replaced by heavy weights, e.g. of several tons, raised up respective vertical guide shafts via a chain or cable system. The plant allows energy to be obtained from natural sources with intermediate energy storage to allow electrical current to be provided cheaply when required.
Patent DE-3020359-A1 (DE)
Inventor: WOLLNIK HERMANN PROF DR
IPC: A61B5/00
Filed: 1980-05-29
Abstract: The method for picking up and representing thermographic images of biological or technical structures, allows the sensing of abnormal temperature repartitions even when they are very low or when the corresponding areas differ very slightly as to their temperature values with respect to adjacent temperature values. According to this method, the temperature values for each image point of a thermogram are digitally picked up and recorded and the pitch of the local temperature variation is calculated, that is to say the temperature gradient for each image point in relation to its temperature and to the temperature value measured for the point adjacent thereto. For a selected image area, the local repartition of temperature gradients is represented. Abnormal temperature repartitions may thus by sensed, from such representation, where important temperature gradients exist.
